portentosum by most TF could be considered as bioindicators of 40K. Taking into account that the annual radiation dose of 40K due to the average consumption of mushrooms analysed (0.15 μSv/year) is very low, it can be concluded that the consumption of these mushrooms does not represent a toxicological risk for human health. Finally, according to the total K content, from the nutritional point of view, these mushrooms could be considered as a potential source of potassium for the human diet.The syntheses and characterization of fish scale biochar magnetic composites (FSB@Fe3O4) and their applications in the removal of indigo carmine dye from effluents are described. Preparation of the fish scale biochar magnetic composites, FSB@400 °C-Fe3O4, FSB@600 °C-Fe3O4, and FSB@800 °C-Fe3O4, was done following the chemical co-precipitation method. The adsorbents were characterized using peak optical absorbance, functional groups, magnetic strength, surface morphology, particle size, elemental compositions, surface charge, surface area, thermal stability, and crystalline phase, using ultraviolet-visible spectroscopy (UV-vis spec), Fourier transform infrared (FTIR) spectroscopy, vibrating sample magnetometry (VSM), transmission electron microscopy/scanning electron microscopy (TEM/SEM), energy dispersive X-ray (EDX), point of zero charge pH (pHpzc), Brunauer-Emmett-Teller (BET), thermo-gravimetric analysis (TGA), and powder x-ray diffraction (PXRD) techniques, correspondingly. The potential of magnetic composites for the abstraction of indigo carmine dye from wastewater was determined as a function of the initial concentration of indigo carmine dye, contact time, dye solution pH, adsorbent dosage, and solution temperature. The results demonstrated that the quantity (q) of indigo carmine dye adsorbed onto magnetic composites improved with a rise in initial dye concentration, adsorbent load, and solution temperature. Conversely, lower quantities of adsorbed dye were recorded at higher pH levels. The data fitted a pseudo-second-order kinetic model. The Langmuir isotherm gave the best fit (Langmuir&gt;Freundlich&gt;Redlich-Peterson&gt;Toth&gt;Hill&gt;Sips&gt;Temkin) suggesting a uniformly monolayer adsorption. Adsorption of environmental wastewater samples revealed that all the adsorbents can be used to effectively treat industrial wastewaters. The recycling data established that the adsorbents could be used for five consecutive cycles without significant loss of adsorption capacities.Increasing business organizations are also damaging the natural infrastructure, and researchers are pressing hard on this issue since several decades. Moreover, the studies relating to business organizations only focus on the establishment, development, and success of businesses and paid less attention to the dark trade business expansions, i.e., lack of green innovation and increase in pollution and environment damages. Keeping in view these issues, this study is aimed at investigating the effect of green dynamic capabilities, green practices, and green value co-creation on green innovation in SMEs (small and medium enterprises). This study also tested the mediating role of value co-creation in the links between green practices-green innovation and green dynamic capability-green innovation. Structural equation modeling (SEM) was used, and the mediation analysis was conducted through Preacher and Hayes Approach (2004, 2008) and through Soble test. Empirical results proved that green dynamic capabilities, green practices, and green value co-creation improve the mechanism of green innovation in SMEs.This paper measures the effects on carbon emissions of production scale, composition, technological use, and environmental policy to elucidate the environmental Kuznets curve (EKC) hypothesis, synthesising the propositions of Grossman and Krueger, Q J Econ, 110(2), 353-377 (1995) and Brock and Taylor (2005) for the case of seventy-seven regions of the Russian Federation from 1999 to 2015. To this end, we apply dynamic threshold regression due to its robustness in addressing non-linear asymmetry and unobserved individual heterogeneity issues. Our empirical investigation demonstrates that the gross regional products (GRP) per capita play a threshold role in supporting the EKC hypothesis and non-monotonic scale effect. Modern technologies used in production appear to be the driving factor in explaining the declining portion of EKC and corroborating the technology effect proposition. Our finding also affirms the effect of composition, as the impacts of energy and technology vary with regional economic growth orientations (e.g. among manufacturing, agricultural, mining, and trade zones). Environmental policy stringency is found to be effective in curbing regional carbon emissions. We provide several policy implications based on the results.The widespread use of pesticides contributes to their existence in the environment. The compounds with photocatalytic activity in environmental matrixes play a significant effect on the photodegradation of pesticides. In order to clear the photolysis effects of the main characteristic inorganic metal elements in the of Panax ginseng field soil on fluazifop-p-butyl, a series of tests were carried out. The obtained results indicated that Mn2+ and Sn+ exhibited a significant photosensitization on the ultraviolet photodegradation of fluazifop-p-butyl. Also the high content of VO3- and Mo7O246- in the photolysis system showed a photoquenching on fluazifop-p-butyl, but the low content is a photosensitive effect. However, in the photolysis system, as the concentration of Co2+ and Li+ increases, the photoquenching effect on fluazifop-p-butyl becomes obvious, and no photosensitization at any tested concentration of them.This study investigated the air quality improvement in terms of bacterial and fungal contamination in an exercise room of a fitness center under normal operating conditions. Environmental conditions including air conditioning, ventilation, moisture, CO2, particulate matters, and total number of users were also recorded. In addition, fungal and bacterial load were assessed and disinfection on sports equipment surface was also examined. https://www.selleckchem.com/products/gsk-j4-hcl.html Background bacteria and fungi densities in bioaerosols were in the range of 249?±?65 to 812?±?111 CFU/m3 and 226?±?39 to 837?±?838 CFU/m3 in the exercise room of the fitness center and 370?±?86 to 953?±?136 CFU/m3 and 465?±?108 to 1734?±?580 CFU/m3 in the outdoor air, respectively. Chlorine dioxide and weak acid hypochlorous water aerosols could remove both bacteria and fungi much better than water scrubbing. Contact time of 15 min was sufficient to control both bacteria and fungi to comply with the official air quality standards. User density and carbon dioxide deteriorated both bacteria and fungi disinfection performance whereas temperature was only statistically significant on fungi disinfection.
